Loud sounds tend to startle us. But imagine being surprised by a sound six times louder than you expect. A balloon-borne instrument called ARCADE,
(Absolute Radiometer for Cosmology, Astrophysics, and Diffuse Emission) was supposed to be used to search for heat signature from the first stars to
form after the Big Bang. Instead it found an unexplained "booming" radio static that fills the sky. In July 2006, the instrument launched from
NASA's Columbia Scientific Balloon Facility in Palestine, Texas, and flew to an altitude of 61,000 meters (120,000 feet) where the atmosphere thins
into the vacuum of space. Its mission lasted four hours. The team, led by Alan Kogut of NASA's Goddard Space Flight Center said they found the radio
noise almost immediately. "We were calibrating the instrument, and we saw this big point in the graph. I said, 'What the heck is this — this
shouldn't be here.' We spent the next year trying to make that point go away, but it didn't."

I am supprised these radio signals were not picked up by SETI?

Detailed analysis has ruled out an origin from primordial stars, user error or a mis-identified galactic emission, and the scientists are sure
there isn't more radio sources than we expect. "Radio source counts are well known and they don't even come close to making up the detected
background," said Kogut. "New sources, too faint to observe directly would have to vastly outnumber the number everything else in the sky." Dale
Fixsen of the University of Maryland at College Park, added that to get the signal they detected, radio galaxies would have to be packed "into the
universe like sardines," he said. "There wouldn't be any space left between one galaxy and the next."

"We don't really know what this signal is," said Seiffert. "We're relying on our colleagues to to study the data and put forth some new
theories."

I also started a thread on this after not coming up with this one on a search, anyhow how cool is this? I think six times louder should tell us
something, what I don't know but something is making this noise What is the question

and now you know why we are DUMB oh dont understand the problem MAKE IT GO AWAY I CANT COPE IT MAKES NO SENS.

You misunderstand. This is the scientific method.

I'll explain with the help of Sherlock Holmes. Remember what he told Watson: 'When you have eliminated the impossible, whatever remains, however
improbable, must be the truth.”

So you're a young scientist, listening in on the universe through your radiosonde balloon, and your instruments suddenly pick up a huge signal out of
empty space, where no signal is expected to be. Your heart leaps, your mind starts racing. You've made a new astronomical or cosmological discovery.
Maybe it's the signal we're all waiting to hear - the first call from another intelligence Out There. Even if it isn't something so spectacular,
just some - I don't know, previously unknown solar wind effect or something - your reputation is still made. They'll name the thing after you for
sure. You can barely contain your excitement.

But you're a scientist, and after the first rush of ecstasy your training in the scientific method takes over. You have to convince the world that
the thing you've found is real, whatever it is. Convincing the world, as any ATS conspiracy buff knows, is hard. Hardest of all to convince are your
fellow scientists - they're going to pick your data over with a fine-tooth comb. If there's the slightest hint of error, you're toast.

And you know - from years of unpleasant personal experience - how easy it is to be wrong. Your 'signal' may be a fault in the equipment, a software
glitch, a programming error, or interference from the local radio-cab company. It may be one of those modern demons called 'data artifacts'. It
could be a hundred and one things.

So like Sherlock Holmes, you go through all the possibilities, eliminating them one by one - 'trying to make that peak disappear'. You check the
equipment, reload the software, do everything you have to do. You're meticulous. And with each possibility you eliminate, your conviction grows
stronger - this is the real thing.

Finally, it all checks out. There really is a signal. You can now announce your discovery to the world. And when you do, you do it with pride. You
tell people how hard you worked on it, how real you know it is. You say, 'We tried for a whole year to make that peak disappear, and what do you
know, it's still there! We're on to something here, boys!'

That's the spirit in which those words should be interpreted, I believe.

The heat left over from the Big Bang isn't much. The Big Bang has cooled down a lot in 13 billion years. This heat is called the
cosmic microwave background. You can't 'see' it with telescopes or
gamma-ray detectors. You need to use a radio antenna, tuned to microwave frequencies. Lots of other stuff, like radio galaxies, radiate at even lower
frequencies than this - at radio frequencies, as you might guess from the name.

These guys were looking for stuff emitting heat at radio frequencies.

Now, you know how we turn radio frequencies into sound. We use a radio.

So when they got this crazy radio signal they put it through a speaker and that's the roar they heard, when all they were expecting was the much
softer sound (of the heat) of stars formed soon after the Big Bang.

The black sky noise temperature that the radiometers (very sensitive radio noise receivers) measure, is calibrated using an external blackbody
calibrator that is cooled close to 2.7K temperature. This is basically the same idea as on some large radio telescopes. However, if the calibrator is
- for some reason - at slightly lower temperature than it is supposed to be, all signals from the sky would appear "louder" than they actually are
as they were calibrated using an incorrect reference noise standard. The warmer the calibrator is, the more it emits radio frequency noise. And the
cooler it is, the less noise it emits. There could have been some unprecedented inaccuracies in the calibrator temperature measurement, which may have
resulted in noise levels higher than expected measured in the sky.

The ARCADE supposedly measured a doughnut-shaped piece of sky as its antennas had quite a wide beam and the instrument rotated all the time around its
vertical axis. Therefore it was basically measuring a large chunk of the sky, not a single point. Still it was measuring a higher-than-expected
background noise level from this entire area. This elevated noise level has not been measured using earth-bound radio telescopes, although they have
their limits of measuring very low noise temperatures due to the radio noise created by the lower atmosphere.

One option would be that they were playing with HAARP just at the same time as the ARCADE experiment was taking place. As the HAARP is supposed to be
an ionospheric heater, it would probably have resulted in somewhat elevated radio noise levels if any precise black sky background noise measurements
had taken place at the same time.

But of course, the overall background noise level of the deep space might actually be a couple of decibels higher than it is supposed to be. This can
only be verified with a precise instrument that is located high enough and has narrow-beam antennas that can be turned to any direction at will: a
space-borne radio telescope. With this instrument it would be possible to find out if there are locations with considerably higher background noise or
if the noise is uniform. I don't now remember if there have been any such satellites to this day, but at least the Russians were supposed to launch
their Radioastron satellite already in the 1990s. So far they haven't. More than ten years ago I used to work for a very small Finnish company who
designed the 22 GHz radiometer for that exact satellite...

This is just another proof that we know very little of the entire Universe. All we have are just theories that collapse every time we discover
something new. As mentioned in the Article, the information was released after 2 years…. I wonder how many more unexplained discoveries they have
made and not disclosed just because it might put into question common believe and theories?

The powers that be don't do things half-way, so you can bet that ALL the unexplained discoveries they have made and not disclosed because it might
put into question common belief and shake the foundation of what we believe keeps us safe.

Acts 2
19 And I will show wonders in the heavens above
and signs on the earth below,
blood, and fire, and vapor of smoke;
20 the sun shall be turned to darkness
and the moon to blood,
before the day of the Lord comes, the great and magnificent day.
21 And it shall come to pass that everyone who calls upon the name of the Lord shall be saved.'
